my friend and i were having a conversation and a so called stroker kit came into play
is this real?
can i really make my 3.0 into a 3.4 liter with a longer stroke??
if so i would be very interested in this, anythoiughts let me know please

They exist... just google "7mge stroker kit" (or "7mgte stroker kit" if you have a turbo).. here's the first one I found, sure there's some cheaper...

however, from the spec's mentioned, I'd imagine you'll want to up your injectors and possibly your fuel pump and rails (but not sure bout that). However, if that's done in part of the kit, no worries.. Good luck, I'd love to get that much power out of my supra... atm, I think I'm gettin somewhere around 180-200hp :\.. but she's in no condition to dyno, still pretty much stock with quite a bit of sluggishness..

The gains are pathetic and the MKIII has long enough of a stroke as it is. It's a complete waste of money.

From everything I've seen posted on all the various fourms that N/A generally comes in between the upper 140's and the lower 160's (at the wheels). Some people post results that are wildly higher, but almost all of them were tested using brands of dynos which are agreed by the masses to always report high and over optimistic results including DynoJet. In all actuality ALL dynos vary from eachother (even the same brand and model), they can ALL be skewed (the operator has a number of calibration adjustments available to him and the shop stands to make more money from you if you think every little change you make gets you big enough gains to merit yet another dyno run) and so on. The only way that dynos are reliable is if you ALWAYS use the same one; they don't change the software version; and you always have them run with NO corrections on.... you'll be thoroughly upset at the results, but the next time you dyno there you'll have a much more realistic idea of what gaind were made. Also, keep in mind that a car's measured output can vary by 10RWHP or so from one run to the next.

I dynod at 164RWHP on a very healthy N/A running a 3.5"GM MAF. This was untuned and running excessively rich. I don't think I would have done much better with a tighter tune though.

A guy I know pretty well in TN named Alex is running a fully built 7M-GE. .50 over forged pistons, BIG stroker kit, MAFT Pro running S/D (I helped him set it up, that's how we met... he's only the second person to get it running on a N/A), lightweight and balanced forged and cryod connecting rods, lightweight and balanced and bladed crank..... and so on. I think he's putting down 220, maybe as high as 240 at the wheels... that's pathetic given the total investment. He is happy with it though, so that's what matters.

wow, that is pretty pricey per hp gained... I think I'd rather just get a JDM 7mgte swap and start with that much power instead of ending with it.. however, it sounds very nice and something to take pride in.. and for that, I'm still envious and can't wait to hopefully have a mk3 as nice..

what ways would you achieve a so called "45" HP gain??
and cheaper?

Krem · 11-12-2009, 05:13 PM

I don't know about 45 hp... I know NA's don't gain much more HP, at least not in comparison to a turbo... have you tried the cold air intake? cat back exhaust, maybe headers? These are what I've been looking at for my NA... but mainly cause I'm not sure of further upgrades for a smaller budget.

The stroker kit blows man ! youd be better off taking your block to a machine shop and bore it to 3,5. and upgrade your injectors and rings and rod bearings !
Port polish the head and see the difference ! or to get an idea, check out my profile or other posts, youll see what I have in mine.

It takes a 101mm stroker kit and a bore of 86mm to reach 3.5l.... and the cylinder walls are as thin as you could safely go. You can't reach 3.5l without a stroker kit.

With a stock stroke of 91mm you'd need a bore of 91mm... you'd be able to see through the walls at 87mm.
