my name is ervin, i live in the states. have some wicked plans for a 1.5, currently driving a 400awhp mistubishi evo 8. looking for 550-650rwhp pump gas 1.5 for highway stints, but mostly to attack the landspeed record of 217.4.

i am married, no kids, work for the army as an xray tech.

plan on bringing total wet weight down to less than a ton, the honest goal is 1800 lbs, 2000lbs with driver.

new to mr2's but always loved there lines. also new to miship design, but i really like the idea of having a high HP car with short wheel base and an engine placed over the rear wheels

i am kinda wondering what rev1,rev2, and rev3 are, are they hp stages?

[djdna2000]

Hi Ervin, sounds like a nice Evo you have there, they are very capable cars! They are very popular over here in the UK with lots of tuner support, Simon Norris of Norris Designs is pushing 1000 bhp in his now I think.

The rev 1/2/3 refers to different model revisions of the mk2 over the years. They don't really apply to the US as you never got the rev 3 onwards models at all cos of emissions regulations or some such crap.

I'm more of a GT4 (alltrac) man but I can tell you that the rev1, rev2 had the 2nd generation 3SGTE engine as found in the US mk2 MR2 turbo, then in 1994 the rev 3 was introduced with the 3rd generation 3SGTE (this was the engine that the States never received, though there are a fair few guys who have done a swap in their mk2s). Rev 4,5,6(?) had the same engine but various body facelifts etc I think.

gen 3 is your best bet as a base for high horsepower: better pistons, bigger valves, longer duration cams, better intake/exhaust manifold design, better head cooling, steel headgasket, bigger/more efficient turbo, better ECU etc etc. However one mamy be difficult (read: expensive) to sort in the US so the standard US turbo engine can be brought up to speed pretty quickly.

thanks for the info

i already have a 3rd gen clip, but i am curious as to whether or not the head flows better, also i have been told i will need the gt4 tranny from st205 on for my 200 mph+ plans, is this a straight swap BH to BH or will there be fabrication

i plan on rebuilding the entire engine with forged internals, and also plan to keep everything as light as possible. i also plan on rebuilding the head, which is why i ask if the 3rd gen head flows any better than a 2nd gen

honestly the only toyota i have ever worked on/owned was a 76 celica gt with a 20/22r which made a whopping 11.5:1 compression and 200 rwhp, quite a fun car

hi ervin,welcome to the forum,you cant use the gt4 tranny on an mr2,its gear linkages are on the wrong side and it has a transfer box on it so no good....a good rev3 turbo tranny should be good for whatever you throw at it i would have thought.

[podge]

mmmmmmm another psyco welcome ervine i look farward to your swap

[wangan_x]

thanks for the welcomes guys

i was told i needed the gearing from a e251 tranny, or was e51

not the tranny just the gears, are there any options for lower final drive gearing on mr2's?

[Paul Woods]

ah right im with you now....ive heard you can use the gearing from a manual V6 camry in the E153 casing for excellent results,sadly no manual camrys in the uk :cry:

[nik]

:shock:
where do all you nutters come from..
welcome to the asylum..
those are nice numbers you have and i can honestly say a 3sgte powered mk1 is a bonkers machine to drive..being a speed freak youll def appreciate it..
i think if youre serious about reaching the 200mph mark (which i am sure you are) youll need to do some aero work on the front of the mk1 as they do tend to lift above 120mph..add 80mph to that and youll probably be airbourne..!! so thatll be the land speed record out the window..
stick around and grab a grinder..

[wangan_x]

i plan on designing an undertray diffuser, so that there is no turbulent air underneath. i also plan on ordering/designing a splitter and if that isn't enough i will add canards

so i think it should be ok, mind you this will be a full build up.

actually i heard that you can use camry gears to, but alas, i heard there top speed would only be 195, and i am looking for 200+, so unless there is a final drive modification that would leave me short

[Gary Symons]

200mph Mk1 :shock:

I think you will fit right in here :D , we need lots of build photos though.

top speed will also depend on redline of your engine. It's possible to raise the redline to over 8,500 if the motor is built properly, which should assist in reaching 200mph.
You should probably also look into venting the area behind the radiator out the bonnet, as this will significantly decrease front end lift at speed

[wangan_x]

ok thanks for the info, as for redline i will be fully building the bottom end with forged everything, looking at a 9.5k redline, unless its possible to up it to 10k, that would be pretty frickin awesome, a 3sgte that high in the rpms

btw i heard someone ran a 9.5k redline on a stock bottom end but lost an oil pan or something, otherwise it withstood all the abuse

[Driftin_AW]

9.5k on the stock bottom end wouldn't last long at all.
you need to get pretty serious to reach those levels. I've heard of people putting plates between head and block and using custom rods to reduce the rod ratio, and you'll definitely need to have the head completely rebuilt with stronger valve springs, and it probably would be beneficial to go to 1ZZ-FE shimless buckets to reduce valvetrain mass. Will also need to run different oil and water pumps as I believe the stock ones cause cavitation at high RPMs.

[wangan_x]

i don't plan on stock bottom end :lol: just saying i heard its possible

i am fully building the engine, forged internals,ti sleeves if they sell em, sc61 turbo, a2w ic(although FMIC isn't out of the question)272 cams, ti valves spring retainers, e153 tranny cryotreated, full suspension, splitter, canards, raised rev limit, either Hydra or AEM EMS, 80mm TB, lateral intake manifold, 750 injectors, 30 psi

fully stripped interior no a/c,radio,cruise, no power anything, lightweight 7 point cage, sts

[lodgeman]

i dont know if you have seen this link but 207mph in a 1.6 engined mr2
11000 rpm at 45 psi boost!!! :shock:
wow!!!

If you get the mk1 to 200mph you'll have to get the body to be adjusted coz the chassis flex alone at that speed could twist the car. Reinforcements would need to be put in place. You'll have to adjust the downforce front and rear too. :? Maybe a bit of added weight will help aid grip.

Can imaging you taking off whilst hitting the 180+ speeds.... :lol:
